How does water quality affect food?

Water quality can be affected by poor planning of industrial sites, animal farms, and barnyards and feedlots. Until recently, the type of water source has been indicative of the potential risks of contamination. Poor water quality can affect the quality of food crops and lead to illness in those who consume them. For example, the water may contain germs that cause human disease. Irrigating crops with contaminated water can then lead to contaminated food products which lead to illness when eaten. Groundwater, for example, has been considered one of the safest sources of water. However, depending on field location and field size, it may not be possible to use water from these sources for irrigation.

How does drip irrigation work?

Based on your water schedule, pumps draw water from the main tank up into irrigation lines above the four rows in the cultivation area. Drip emitters positioned about the individual plant panels slowly water the plants, with gravity pulling the enriched water from the top of the panel to the bottom with a cloth wicking strip. Any excess water is caught in gutters at the bottom of the row and redirected back into the main tank.

Why is agriculture bad for you?

Agriculture is not only responsible for polluting water, but it can also make that water dangerous. Contaminated agricultural water is a huge source of E. coli and other food-borne illnesses. This happens often because large industrial farms use manure sourced from meat and poultry farms. From there, pharmaceutical residue, heavy metals, and harmful bacteria can all be leached from the manure. In one case, this contaminated water can flow into a nearby water source and be ingested by nearby residents. In the other, that contaminated water can be used to irrigate crops, making the crops themselves carriers of disease. This is likely the cause of the many E. coli outbreaks commonly seen in staple vegetables like romaine.

According to the 2017 Census of Agriculture, farms with some form of irrigation accounted for more than 54 percent of the total value of U.S. crop sales, while irrigated land accounted for less than 20 percent of harvested cropland. Irrigated crop production helps to support local rural economies in many areas of the U.S., and contributes to the Nation’s livestock, food processing, transportation, and energy sectors.
